The Cardinals rookie probably wasn't suppose to be streaming that speech live...

(NOW) - This is a side of St. Louis Cardinals manager Mike Shildt we haven’t had the joy of experiencing until now.

After the 13-1 stomping of the Atlanta Braves in Game 5 of the NLDS, Cardinals outfielder Randy Arozarena posted an Instagram Live video of Shildt addressing his team in the clubhouse. It's seriously Not Safe For Work!!

Mike Shildt:

“The [Braves> started some shit. We finished the shit. And that’s how we roll. No one fucks with us ever. Now, I don’t give a fuck who we play. We’re gonna fuck them up. We’re gonna take it right to them the whole fucking way. We’re gonna kick their fucking ass.” pic.twitter.com/2J7jyJc60O
